Man throws his grandfather down a flight of stairs during home invasion causing him to lose a finger

A man was arrested, charged and convicted of assault after throwing his grandfather down a flight of stairs during a home invasion, prosecutors in the United Kingdom said.

Two men and a woman appeared at the St. Albans Crown Court, and were jailed for a combined total of 39 years and 9 months in connection with a violent burglary in Cheshunt.

The incident occurred around 12:30 a.m. on Tuesday, at a property on Penton Drive.

The resident, Jack Sibley, armed himself with a decorative knife and went to investigate noises he heard coming from inside his home.

Two intruders, who disarmed him, assaulted him with the knife and pushed him head first down the stairs. The two intruders then made off and fled back to Stevenage, empty handed.

A neighbor heard the victim calling for help and went to help him. He found the victim at the foot of the stairs in a pool of blood and with serious injuries.

He called the emergency services.

The 82-year-old victim received significant injuries, which included multiple cuts to his scalp and face, a stab wound to the chest and the loss of a finger.

He almost lost a second finger, and also had a dislocated shoulder and facial fractures. The knife used in the burglary was later found dumped in Great Wymondley.

All three were found guilty in connection with the attack.

21-year-old Jack Sibley, the grandson of the victim, was found guilty of conspiracy to rob, causing grievous bodily harm with intent and doing an act intended to pervert the course of justice by burning the gloves he wore on the night of the incident.

He was sentenced to 19 years in prison.

22-year-old Warren Reid of Seaton Road, Luton, was found guilty of conspiracy to rob, causing grievous bodily harm with intent and doing an act intended to pervert the course of justice by hiding the knife used during the incident.

He was sentenced to 19 years and 9 months in prison.

48-year-old Lorraine Sibley, Jack Sibley's mother and the daughter-in-law of the victim, was found guilty of doing an act intended to pervert the course of justice by lying to police about cuts on her son's hand, which he had sustained during the incident.

She had claimed that he had fallen onto some glass. She was sentenced to 12 months in prison.
